This younger version of Professor Echo looks strangely familiar.
During the mission Catch Professor Echo once and for all, this strange character will reveal some interesting clues about Professor Echo and about himself:
Professor Echo: I know the world you came from was destroyed, but it doesn't have to happen again!
Professor Echo: You've got to stop Villain!
Dr Aeon?: Wait...
Dr Aeon?: You're me?
Dr. Aeon?: Villain? But you're dead! Or maybe that hasn't happened yet...
Professor Echo: Get out of here, Aeon. This is my fight.
Professor Echo: Just remember this moment... When it's your turn.
